2007-12-04 Emmanuele Bassi <ebassi@gnome.org> * glib/gchecksum.[ch]: Add GChecksum, a generic wrapper around various hashing algorithms. At the moment, the MD5, SHA-1 and SHA-256 algorithms are supported. (#443648) * glib/glib.h: * glib/Makefile.am: * glib/glib.symbols: Build glue for GChecksum * tests/Makefile.am * tests/checksum-test.c: Add test suite for GChecksum. svn path=/trunk/; revision=6042
